MLPA and DDISH in HER2 non amplified and amplified breast carcinomas. Two exemplificative BC a-d showing respectively a HER2 normal gene status a by MLPA (mean value 0.82) and b by DDISH (ratio < 2.0) and HER2 gene amplification c by MLPA (mean value 8.45) and d by DDISH (>6.0 s/n, ratio ≥ 2.0). Scale bar = 30 μm
